Guidance and Manufacturer's Declaration - Electromagnetic Immunity:
This device is intended for use in the electromagnetic environment specified below. The user of this device should make sure it is
used in such an environment.
Immunity Test
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a/ The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz;13,553 MHz to 13,567
MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
b/ The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are
intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought
into patient areas. For this reason, an additional factor of 10/3 is used in calculating the recommended separation distance for transmitters
in these frequency ranges.
c/ Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur

Electromagnetic Environment-Guidance
Portable and mobile RF communications
equipment should be used no closer to any part of
this device, including cables, than there
commended separation distance calculated from
the equation applicable to the frequency of the
transmitter.

Where P is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in each
frequency range d .
